    • Great gift for the Harry Potter fan
The colors were spot on. And the color change happens fast and last as long as your coffee is still hot. Cleans up easy, but we only hand wash.

    • Looks great and is fun to watch it change/morph
Color: I Solemnly Swear
Bought this as a birthday gift for my daughter who is a lifetime Harry Potter fan. She doesn't drink much coffee, but does drink hot tea. Fortunately the cup doesn't differentiate one hot drink from another. But yeah, the cup looks great when it's cold and it's fun to watch the scene change when you pour in your drink of choice. 10 out 10 would buy again. ... show more

    • Love this mug
Color: I Solemnly Swear
As an avid Harry Potter fan, I love this mug. It's pretty big so I don't have to refill it when I'm having a cup of tea. It doesn't leak, which is pretty important since most likely you're drinking a hot beverage out of it. It's so cool to watch the mug decor change to the marauders' map so I definitely think it was worth the money I spent to buy it. Super easy to clean too, just wash it by hand with soap and water or just throw it in the dishwasher since it's pretty durable. I love it and I think you will too. ... show more

    • Really fun for a Harry Potter fan!
Color: I Solemnly Swear
This is a great, well made mug. It’s a nice size as well. The only slight downside is that the liquid has to be extremely hot for the mug to change to where you can see it well. Overall, it was a great gift!
